PATTERN AND GUIDE STRIPI Filed oct. 51, 1927 `lltatented Apr. l5, 1930 NITED PATENT FFICE WATTERN AND GUIDE STRIP application nlel number 31, 1927; Serial No. $30,116.,

I'llhe present invention relates to pattern and guide strips such as are used in laying plastic loorings and has for an object to augment the strips with anchor and gauge elements to retain the strips troni all displacenient,

Another object ot the invention is to equip the guide strips with anchoring and gauge elements which are so Jlornied that distortion to along'the parallel edges ot' the strip, during manufacture, is prevented,

A further olo'iect ot the invention is to torin anchor and guide elements on the strip in such a manner that lateral tiltinfn oit-the strip,

l5 either when the latter is irnlaedded in the screed coat or when the mosaic coat is poured, is elilectively prevented.

@ther olijiects oit the invention will he apparent trom th'e following description of the p 20 present preferred terms ot the invention,

-talren in connection with the accompanying drawings, wherein: 1

lligure l is a fragmentary side elevational view ot a strip constructed in accordance with Q5 the present invention, showin the anchor and guide plate turned outwar ly into opern ative position;

liigure 2 is a longitudinal sectional view oi'j the same; and, l

ltligure 3 is a fragmentary side elevational view olf a strip constructed in accordance with the present invention, showing the anchor plate in an inoperative position.

lin the drawings, a strip t is illustrated llll which, except tor the anchor plate hereinafter dcscrihed, is ot standard construction. The strip has horizontally' arranged incisions 5 cut therein, which are parallel to the longitudinal edges ot thestrip. Vertical incisions d entend lroin the terminals oli' the incisions 5, each ot which is intersected, midway its ends, loy a pair oi incisions l. By cutting the strip in i this manner, a plate 8 is stamped in the strip, portions ot' the ends oi' which issue into riblcll lions or straps tt rllhe outer ends oit the rilalions merge into the body oit the strip.

lin ose, the plate 8 is turned a quarter ot a revolution, so as to project the lateral edges 1 thereol beyond the sides ot the strip. rllhis lm provides an anchoring and gauge portion on titl ythe projecting portions ot the anchor plate and permitted to dow through the upper openingd.. lgonsequently, when the plastic o5 material hardens, the screed and mosaic coats are loondedtogether into a snlostantially rnon# olithic structure.

lt is manifest that the anchor plates may lie twisted into an operative position on the 70 job, thereby permitting the strips. to he shipped dat. lJl/Yhen the plates are twisted into an operative position, the upper and lower' races thereoll are parallel to the edges oit' the'strips. Not only do the plates anchor ld the strips, tout lay reason of their protruding portions at directly opposite points on the strip, lateral tilting ot the plate is prevented. Additionally", the plate may he stamped outat any portion oil the strip desired intermediate the edges to regulate the depth ot the mosaic or iinishing coat. rllhis form oil strip provides an exceedingly simple and ellective structure without in any way militating against the normal use ont the strip and providing a structure which may he manniiactured at a very low cost.

What is claimed is:

l. A guide and pattern strip including a strip body having straight edges and equipped with portions struclt out trom the loody and projecting in a horizont-al plane at directly opposite points on the strip intermediate said straight edges.=

2. An anchor and gauge tor guide and pattern strips including a strip having straight edges and equipped with a plate extending through the strip intermediate said edges, the faces ot which are parallel to the longitudinal axis ot the-strip, the lateral margins ot said plate projecting beyond the side's of the strip.

3. An anchor and gauge for guide and pattern strips including a strip equipped with a plate, twisted in the body of the strip with portions projecting on opposite sides of the strip, the faces of the plate being parallel to the longitudinal edges of the strip.

4. A guide and pattern strip including a strip having straight edges, a plate formed on said strip intermediate theedges thereof, said strip having openings above and below the plate.

5. A method of making a pattern and guide strip consisting in incising the strip intermediate its marginal edges to define a plate,4

after which the plate is twisted to project portions thereof on both sides of the strip, the faces of which are parallel to the longitudinal axis of the strip.

6. A pattern strip including a strip body, a portion of said bod being bent out to project on both sides o the strip, the faces of said bent out portion being parallel to the longitudinal axis of the strip.
